The ROCCAT Lua optical gaming mouse is designed with budget gamers in mind. The ROCCAT Lua`s buttons all use high quality Omron switches to ensure durability. It has an ambidextrous V-Shaped mouse that is ideal for palm-grip users, although it could be used with any grip. The R2 Pro Optic sensor provides seven dpi modes, ranging from 250dpi to 2000dpi, that are easily switched, offering an excellent range of speed settings to suit any play style. The scroll wheel has tactile feedback for accurate scrolling and gameplay. The ROCCAT Logo on the mouse is lit by a switchable LED, allowing it to be on, off, or a breathing pattern. The LED setting can be switched using the included driver/software, along with the ability to customize the sensitivity and what each button does."
